I have previously written about websites I like to use to gather free images to use on blogs, wikis, on websites and in presentations.
4 Free Photos is another great website that offers free images, which students and teachers can use without having to worry about breaking copyright laws. The images are well organised under different categories and you can also search via keywords. They do ask that you provide a small link or reference to acknowledge the original creator of the image.
It’s important to teach students to respect copyright especially as more start to publish via social media and web 2.0 tools.
